Revert "block: all blk-mq requests are tagged"
commit e999dbc254044e8d2a5818d92d205f65bae28f37 upstream.
This reverts commit fb3ccb5da71273e7f0d50b50bc879e50cedd60e7.
SCSI-2/SPI actually needs the tagged/untagged flag in the request to
work properly. Revert this patch and add a follow on to set it in
the right place.
